Title: Improvements in or relating to silencers for gaseous currents
IPC: F01N1/02
Filed: 1941-03-05
Abstract: 547,710. Silencing gaseous currents. SULZER FRERES SOC. ANON. March 5, 1941, No. 2984. Convention date, March 8, 1940. [Class 7 (ii)] For silencing a pulsating gas stream, for example, in the exhaust or suction pipe of an internal combustion en-' gine, or in a compressor, ventilating-plant &c. the gases are caused to flow over one or more perforated plates along a passage which is of constant cross-section and is deflected at least once through an angle of 180 degrees, so that the sound waves are damped by interference between the gas streams at opposite sides of the perforated plates. In its simplest form the silencer may comprise a passage bent back upon itself over a perforated plate, which thus lies between the original passage and that formed by bending back. Fig. 4 shows a practical form comprising a casing 1 containing perforated plates 11 which cause gases entering at 2 to be doubled back upon themselves, first at 17 and then at 18, with outlet at 3. The casing may have a cooling-jacket 15, cleaning openings 19, and a drain 16. Fig. 6 shows another arrangement of the perforated plates, causing the gases to turn through 180 degrees at 20 and 21. Two silencers, either as shown in Fig. 4 or as in Fig. 6, may be arranged in series in the same casing. The total length of the path along which the gas flows inside the silencer preferably equals a multiple of the wave length of the lowest frequency to be eliminated.

Title: Improvements in or relating to load transportation means
IPC: E02F9/04
Filed: 1958-01-29
Abstract: 875,504. Propelling vehicles. EISENWERK WESERHUTTE A.G. Jan. 29, 1958 [Feb. 2, 1957], No. 3004/58, Classes 79(3) and 79(5). The forces exerted on striding mechanisms for transporting a load are controlled by a device corresponding geometrically and in arrangement with the mechanisms and carrying,out the movements of the latter or similar movements on a smaller scale. The load 11, Fig. 1, is carried by striding mechanisms in which the angular movements of members 5, 6, 7 about pivots 8, 9, 10 to produce the striding movement are controlled by corresponding members of a smaller control mechanism. On the latter, angular movement of a member 5<SP>1</SP>, Fig. 4, for example, rotates a pulley 17 which is connected by a wire rope 52 to a pulley 17, Fig. 5, connected to a spring- loaded arm 54 carrying electric contacts which engage contacts 75 or'76 carried by the arm 5 to complete a circuit to' a motor 98 which raises or lowers the arm until the contacts separate. The wire rope is provided with a spring to prevent excessive strain after the motion of the arm 54 has been arrested by engagement of the electrical contacts. Movement of the members 6 and 7 is similarly controlled. Each leg 2 of each striding mechanism is connected by ball joints 12..16 and links 3, 4 with a foot 1 and the members 5, 6 and 7. The lower ends of the legs in the control mechanism are connected by ball joints, such as that shown at 16<SP>1</SP>, to a base plate 18 carried by a turntable 21 which may be adjusted by a pinion 22 on a shaft 23 co-operating with a scale 24. Vertical and horizontal reciprocations corresponding to those required at the feet 1 are imparted to the plate 18 by cams 39 and 40 while to enable the load to be turned on the spot a pendulum movement may also be imparted to it by a third cam (not shown). The cams are carried on a common shaft driven by a motor with a variable speed gear and are axially adjustable with a non- uniform cross-section so that the motions imparted to their followers may be varied. Linkages 26, 28, 30, 32, 40, 41 and 33, 35, 36 and 37 are connected to each other by a horizontal joint 'and transmit the horizontal and vertical reciprocations to the base plate and turntable. The linkage between the third cam and the base plate includes a parallelogram so that the pendulum motion may take place independently of the other movements. An alternative mechanism for actuating the legs 2<SP>1</SP> of the control mechanism is described, the legs being coupled to those of the striding mechanisms by electrical means. An arrangement in which the legs of the control mechanism are more closely joined than those of the striding mechanism and are engaged by arcuate slots having their centres displaced from the turntable centre is also described. The control mechanism may be coupled to the striding mechanisms by pneumatic, hydraulic or electrical means, including radio,

[Class 80 (ii)] [Also in Group XXVI] In mechanical power transmission systems for coupling a prime mover to a load. e.g. a diesel engine to its vehicle wheels, of the kind providing a plurality of separated velocity ratios which are selectively engageable to match the speed and torque of the engine with the load conditions, means are provided for automatically effecting a gear change from a lower to a higher gear in response to an increase of engine speed above a predetermined value, the means being arranged to reduce the torque in response to the increase of speed and to initiate the gear change only if the speed of the engine does not fall below said value when driving through the gear in use at the time with the engine torque reduced in relation to the torque at which the engine will operate upon engagement of said higher gear proportionally to the relation between the velocity ratios of said lower and higher gears, whereby prior to the initiation of the gear change, the torque applied to the load in said lower gear is reduced to the value which will be applied to the load if the gear change is effected and if the reduction of torque causes the engine speed to fall below said value in consequence of the torque in the higher gear being insufficient to maintain the load in operation at the prevailing speed, the gear. change will be prevented. The mechanism is described in connection with Figs. 1 and 4 of Specification 546,821 and the main claim is for the subject-matter set out above.

Abstract: 983, 952. Read-only stores. INTERNATIONAL BUSINESS MACHINES CORPORATION. Jan. 11,1962 [Jan. 27, 1961], No. 3238/61. Heading G4A. [Also in Divisions H1 and H3] A read-only memory used e.g. in storing microprograms consists in a set of ferrite cores C 0  C 1  . . . acting as pulse transformers arranged on the periphery of a disc with primary windings on selected subsets of the cores connected each between a pair of conductors taken one from each of two groups of drive conductors mounted on the disc. The two groups of drive conductors consist of radial conductors R N  printed on the top surface of the disc and annular conductors AN printed on a lamination of the disc (Fig. 2). Terminals 9 project through the surface of the disc from conductors AN and receive one end of the primary windings. The other ends are attached to terminals 10 which are connected to the radial conductors R N  through diodes D. There are three forms which the ferrite cores might take. In Fig. 1 U-shaped ferrites are each mounted with the limbs projecting from a recess in the periphery of the disc. The primaries are wound to pass between the limbs if the core is to be energized or to pass over a post 4 if the core is to be skipped. Ferrite bars bridge the limbs and are held in position by clips 3 attached to the posts 4. As shown in Fig. 3 the disc periphery carries nylon bushes 14 having projections 14a about which the primaries are wound. After this has been done a ferrite bar 16 is inserted and is capped by a U-shape ferrite member 18 held in place by a clip 17. In a third embodiment the cores may comprise teeth formed from a solid ferrite block comprising the disc periphery and grooved to accommodate the primaries. The cores are capped by ferrite bars as in Fig. 1
